Specification of Letters Patent.

Patented Nov. 13, lenti.

i pplication filed August 30,1905. SerialNo 276.470.

To all-whom it may concern: l

Be it known that l, lsIDonE C. BANDMAN, a citizen of the United States, and a resident ci the city-oiNew York, borough ci Manhattan, in the county and Statie of New York,

have invented a new and Improved Stationlndicator, of which the following' is a full,-

clear, and exact description.

My invention relates to ay device adapted to be used for many purposes, but -particularly applicable for announcing lstations 'on railways and-the' like. While capable of use on all kinds oi railways, street-cars, and the like, it is especially designed for that character of trains in which the gates or doors cannot be opened except when the train stops at a station-as, for example, lthe ordinary elevated and subway trains.

Among the objects of the invention are the provision of means whereby when the gate or door is opened or closed a movement is given to certain parts oi the device so as to change the sign displayed, also to provide for an# nouncing the stations in regular order, either forward or backward, according tothe direction of motion of the train, and the provision of very simple Vmeans for shifting the o erating mechanism in such a way as to c ange .the direction oi motion of the sheet bearing the names of the stations.

Further objects of the invention will appear below.

` Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the gures.

Y Figure 1 is a perspective view of a portion of a-car, showing outside connecting devices for the indicator. Fig. 2is a front view of an indicator, partly broken away, to show interior construction. Fig. 3 is a rear view, also partly broken away and in section and showing interior construction. Fig. 4 is a sectional view on line 4 e of Fig. 3, and Fig. 5 is an end view or" a support for carryingfthe station-indicating sheet.

Elevated and subway trains are usually provided withgates whichl are not intended to be opened except when the 'train is at a station. Therefore the opening or closing of the gate is an indication ci Vthe passage through a station, and the number f stations passed will be shown by the number of times 'the gate has been opened and closed.

In the drawings l have indicated a gate 10, which is-provided with a link 1,1, a slide 12, and an operating-lever 13 of the ordinary construction. Connected with the slide 12 is a `ilexible member 141, whichis roperly uided -to a-position near the top ci t e car, w ere it is connectedvwith a lever 15. This lever is oscillatably mounted upon a'shaft 16 and carries a pair of pawls 17, whichare forced' by springs 17.8' into engagement with ratchetwheels 18 and 19 near opposite ends of the shaft 15. 'These ratchet-wheels areiplaced with their teeth facing in opposite directions, so that as the lever is vosc'illa'ted about the shattit will draw one of the pawls 17V over. one oi. the ratchet-wheels without operating it, but will engage the othery pawl with the teeth of the other wheel so as to turn the second ratchet-wheelwith the lever in one direction. g

Connected: .with the 'ratchet-wheels lare cones 2U 'and 21. These cones are-adapted to engage a clutch member 22, and, in fact, they form companion members for said clutch member. This clutch member is rigidly connected' with agear 25, which in turn is con- This l nected with a pinion 24 on a shaft 23. shaft carries a snpport 26, which l have shown as being square in cross-section and extending across `the indicator. support is provided with means for engagingand winding up 'a sheet 27, carrying the names of the stations. This means in the present instance is shown in the `form of a series of pins 28 for engaging periorations 29 in the edge ci the sheet. This sheet is designed to be wound up upon a drum 30,

Imounted on a shaft-31 and provided with a spring 32jfor normally keeping the sheet' wound upon the drum when not operated upon by the mechanism described above.

l have shown a groove 33 connected with each of the ratchethwheels 18 and 19, and in these grooves are adapted to engage a pair of iingers 3e, mounted upon a sliding bar 35, having a handle 36 on the outside of the indicator. l have shown the indicator as being mounted ina casing 37, through a slot 38 of which the lever 15 projects. This cas-y ing is also providedwith an opening 39 o posite the support 26, through which the s` eet 27 can be observed by the passengers.

The operation of the device is as follows: When thelever'l is operated to open the gate, the dexible member 14 is pulled by the slide 12, which depresses the lever l5. This operation ci? the lever about the shaft 16 re- IOO IIC

senseo pulled out or pushed in, one ofthe cones or 21 will engage with the clutch member`22 and the other Will. he free from' it. Consequently the operation of the llever,through a complete oscillation will operate through one of the cones to the clutch member 22 and rotate the Wheel 25 in either direction, according to the position oi' the sliding rod 35. This operation of the Wheel 25 is timed to rotate the support 26 through a sufficient part of a revolution to display a diderent name behind the opening 39. in the present instance it would rotate it through an arc oi ninety degrees. it will he seen from this description that every time a train passes the station the name of that station is removed from the observation of the passengers and that of the next station is displayed, all the operations being performed automatically and requiring no attention on the part of the loraieman or conductor.

Having thus described my invention, l claim as new and desire to secure by Letters Patent# A station-indicator, comprising a movahle support, a shaft connected with the support, a pair oi ratchet-Wheels, a lever, paWls on the iever, said-parvis heing'adapted to rotate the ratchet-Wheels in opposite directions, and a clutch for connecting one ratchet- Wheel With the shaft and disconnecting the other therefrom.

2. A station-indicator, comprising arctatable support, a Wheel for rotating the support, ashaft on which said Wheel is mounted, a lever oscillatahly mounted on the shaft, a pair of ratchet-Wheels von the shaft facing in opposite directions, a pair of pawls on the lever for engaging said ratchet Wheels, and means for throwing one of saidratchet-Wheels into operative connection with respect to the first-named Wheel and simultaneously throwing the other ratchet-Wheel out of engagement With the first-named Wheel, said means comprising a reciprocalole har.

3. A station-indicator comprising a rotatable support, a Wheel ior rotating the support, a shaft on which said Wheel is mounted, a lever connected with the shaft, a pair of Wheels located on the shaft on opposite sides oi" the rst Wheel, means connected with the lever for engaging the pair oi Wheels, means connected with each of said pair oi wheels for rotating the shaft in one direction, and means for throwing one orn the pair of Wheels into operative connection With respect to the rst-named-Wheel and simultaneously throwing the other oi said pair oi Wheels out of engagement therewith.

, in testimony whereof i have signed my nameto this specification in the presence of tWo subscribing Witnesses.
